Description of problem:
When showing the application level APIs, all the hrefs are using https://<broker_DNS>/broker/rest/application/:id (singular of application), while in the official document (http://openshift.github.io/documentation/rest_api/rest-api-1-6.html#application), the APIs are using "applications" (https://<broker_DNS>/broker/rest/applications/:id). Moreover, the APIs referrer in the documentation are not accessible.

Version-Release number of selected component (if applicable):
devenv_3844
REST API 1.6

How reproducible:
always

Steps to Reproduce:
1. create an app
2. get the API list of this app
3. try to stop the app with the corresponding API http://openshift.github.io/documentation/rest_api/rest-api-1-6.html#application
4. try to stop the app with the corresponding API returned in Step 2

Actual results:
In Step 2, all the app level APIs are using "application/:id" as its suburl, for example,

 "STOP": {
                "href": "https://ec2-23-20-54-119.compute-1.amazonaws.com/broker/rest/application/524795154974f504e3000010/events", 
                "method": "POST", 
                "optional_params": [], 
                "rel": "Stop application", 
                "required_params": [
                    {
                        "description": "event", 
                        "invalid_options": [], 
                        "name": "event", 
                        "type": "string", 
                        "valid_options": [
                            "stop"
                        ]
                    }
                ]
            }, 

In step 3, it fails when trying to stop the app with the official API (applications/:id), and the error is 

<h1>Routing Error</h1>
<p><pre>No route matches [POST] &quot;/broker/rest/applications/524795154974f504e3000010/events&quot;</pre></p>
<p>

On the other hand, it works when using the href returned in Step 2 (application/:id)

    "messages": [
        {
            "exit_code": 0, 
            "field": null, 
            "index": null, 
            "severity": "info", 
            "text": "Application spy27 has stopped"
        }
    ], 


Expected results:
The application leve APIs should be consistent with those in the official documentation of REST API 1.6.
